U.S. Department of Defense Arctic Strategy

November 22, 2013

The Department of Defense (DoD/Department) Arctic Strategy outlines the American military's role in carrying out the National Strategy for the Arctic Region, including maintaining peace and security in a region severely impacted by climate change. The Strategy explains how the DoD will promote security, stewardship, and international cooperation in the Arctic, where the intended “end-state” for this strategy is: “a secure and stable region where U. S. national interests are safeguarded, the U.

Alaska Highway Study: Groundwater Flow, Permafrost Degradation, and Transportation Infrastructure Stability

2013

The Alaska University Transportation Center (AUTC) of the University of Alaska, Fairbanks, supported a research project to study the effects of groundwater flow on permafrost degradation and resulting road instability. The stability of permafrost below roadways and embankments is increasingly affected by warming surface temperatures caused by climate change, but may also be affected by heat transfer from groundwater flow. Studies have shown that groundwater flow can accelerate permafrost degradation by several orders of magnitude compared to thaw caused by heat transfer from the atmosphere alone.

Climate Adaptation and Action Plan for the Norton Bay Watershed, Alaska

December 2013

This plan was developed by the Norton Bay Inter-Tribal Watershed Council (NBITWC) to address climate stressors, risks, and adaptation opportunities for tribal villages in the Norton Bay. NBITWC conducts research, education, and advocacy to protect and restore water resources toward tribal interests. The Council represents four Inupiat Eskimo native villages in the Bay, which is located within the Seward Peninsula in northwestern Alaska. The plan includes an economic analysis and forest and water resources assessments, focusing on the restoration of traditional knowledge as a primary adaptation strategy.

Kenai Fjords National Park – Protection of Exit Glacier Road

September 2012

The National Park Service (NPS) has taken interim and long-term measures to repair and reinforce a one-mile section of the access road to Exit Glacier, the most accessible and popular area of Kenai Fjords National Park, to address flooding damage exacerbated by climate impacts. While flooding is a recurring event in the glacial area, less predictable flow patterns and increased flood frequency due to climate change have destabilized drainage on the road. NPS worked with highway engineers to design an interim solution, using concrete barriers to keep flood waters off the road, while continuing to study long-term stabilization solutions.

Alaska Highway Case Study: Heat Transfer, Permafrost Degradation, and Transportation Infrastructure Stability

2011

The Alaska University Transportation Center (AUTC) of the University of Alaska, Fairbanks, has supported multiple projects to research measures to reduce permafrost thaw and the resulting impacts to roads, specifically along the Alaska Highway (the only road connecting Alaska to the continental U. S. ). Structural damage occurs when the permafrost under road infrastructure thaws. Thermal modeling demonstrates that the stability of permafrost below roadways and embankments is greatly affected by surface temperatures of roadways, and it has therefore been predicted that as the climate warms, permafrost degradation will be a major issue for the design and maintenance of roads in Alaska.

Alaska Department of Fish and Game Climate Change Strategy

November 2010

Recognizing the impacts of climate change, a Climate Change Sub-Cabinet was formed in 2007 to inform the Office of the Governor of Alaska, and to prepare a comprehensive climate change strategy for the state. As part of this effort, each state agency was asked to identify how climate change impacts may affect its ability to meet its mission. Because a changing climate is anticipated to affect the sustainability of Alaska’s fish and wildlife resources and their uses, it is of interest to the department to assess the likely effects of climate change on fish and wildlife and their uses and to develop adaptation strategies to address these effects.

Climate Change and Health Impact Assessment Reports - Alaska

August 2010

The Alaska Native Tribal Health Consortium provides a database of assessments on public health impacts from climate change for communities in Alaska. The purpose of this website is to present climate change impacts that are occurring at a local level, so as to help in the development of adaptive strategies that encourage community health and resilience.

Climate Change in Point Hope, Alaska - Strategies for Community Health

August 2010

This report details the struggles of the community of Point Hope, Alaska to adapt to the impacts of climate change.  Major climate change impacts affecting the community include: changes in temperature and precipitation, sea level rise, erosion, permafrost melt, thinning ice and increased snow accumulation, decreases in water quality and supply, and food safety and security.

FHWA - Regional Climate Change Effects: Useful Information for Transportation Agencies

May 10, 2010

Developed by the Federal Highway Administration (FHWA), this report is intended to provide the transportation community (including highway engineers, planners, NEPA practitioners) with transparent, regional information on projected climate changes and effects that are most relevant to the U. S. highway system. This information is designed to inform assessments of the risks and vulnerabilities facing the current U. S. transportation system, and support planning and project development activities.

Impacts of Climate Change in Flood Frequency Analysis for Transportation Design in Alaska

July 2010

This study addresses whether or not current flood frequency estimates for south-central Alaska adequately characterize true flood occurrences given limited observational data, the influence of natural climate variability on extreme events, and potential climate change. The research is intended to lead to the understanding of regional hydrology while resulting in the least total cost for this aspect of transportation infrastructure in Alaska.
